Description

Technical Field

[0001] The invention relates to the technical field of water area algae removal and oxygenation equipment, in particular to an algae removal and oxygenation machine and a water quality improvement device. Background Art

[0002] Water pollution refers to the phenomenon in which pollutants released by human activities into water bodies exceed their self-purification capacity, altering the physical and chemical properties of the water and its quality, as well as the biological characteristics and composition of the aquatic environment. This affects the water's usability, deteriorates its quality, and even harms human health or damages the ecological environment. In recent years, the large-scale discharge of wastewater such as feed in aquaculture, industrial wastewater, domestic sewage, and agricultural wastewater into freshwater lakes, reservoirs, and rivers has, to a certain extent, led to water pollution and eutrophication, providing a breeding ground for various harmful algae. Cyanobacteria are a particularly serious type of algae that pollutes water bodies. They can produce highly toxic natural toxins (cyanobacteria toxins), which threaten the health of aquatic life and humans. The spread of cyanobacteria has caused significant economic losses to the aquaculture industry.

[0003] Existing algae removal technologies generally use direct manual salvage, spraying algaecides in the water using a surface float device, or installing an ultrasonic device in the surface float device to kill algae. However, manual salvage is time-consuming, labor-intensive, and inefficient. Directly killing algae in the water will leave the bodies of cyanobacteria in the water. The dead cyanobacteria still release toxins and cause secondary pollution. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0034] The present invention proposes an algae removal and oxygenation machine, please refer to Figure 1 The algae removal and oxygenation machine 100 includes a housing 10 , a water spray pipe 20 , an algae removal mechanism 30 , a water pump 40 , a valve assembly and a controller 80 .

[0035] The housing 10 includes a shell 11 and a float 12. The shell 11 is provided with a mounting cavity 11a. The shape of the shell 11 can be cylindrical, square, disc-shaped, or other shapes, without specific limitation herein. The shape of the mounting cavity 11a provided in the shell 11 can be consistent with the shape of the shell 11 or different. Preferably, the shape of the mounting cavity 11a is consistent with the shape of the shell 11, thereby saving material and providing a larger space for the mounting cavity 11a based on the limited material.

[0036] The shape of the float 12 is not limited to a spherical shape. It can also be a ring shape similar to a lifebuoy, or a block-shaped float plate or other structures. The number of the floats 12 can be one, two, three or more than three. The specific number can be determined according to the shape of the float 12.

[0037] The connection method between the float 12 and the shell 11 is related to the structure of the float 12 itself. For example, the float 12 is spherical and is connected to the shell 11 through a connecting rod. For another example, the float 12 is annular and can be sleeved on the outside of the shell 11. The float 12 can also be connected to the shell 11 in other ways, which are not listed here.

[0038] The water inlet end of the water spray pipe 20 extends into the installation cavity 11a, and the water outlet end thereof extends to the outside of the installation cavity 11a. The water inlet end may be provided with only a nozzle for spraying water, or it may be provided with a plurality of water spray holes on the pipe wall for spraying water. The plurality of water spray holes may be arranged at intervals along the circumference of the water spray pipe 20 and also arranged at intervals along the axial direction of the water spray pipe 20. The plurality of water spray holes may also be randomly dispersed, and no specific limitation is made here. The water outlet end and the water inlet end of the water spray pipe 20 may be formed by the two ends of the integrally formed water spray pipe 20, or the water outlet end and the water inlet end of the water spray pipe 20 may be formed by the ends of two interconnected water pipes, and no specific limitation is made here.

[0039] Preferably, please refer to Figure 1 The water outlet end of the water spray pipe 20 is provided with a rotating nozzle, and a plurality of water spray holes are provided on the circumferential side of the rotating nozzle. The rotating nozzle is rotatably connected to the water outlet end of the water spray pipe 20. The rotating nozzle is also connected to the driving motor through a connecting shaft extending axially along the water spray pipe 20 and passing through the water spray pipe 20. The driving motor is fixed in the mounting cavity 11a. The rotating nozzle can rotate relative to the water outlet end of the water spray pipe 20 under the drive of the driving motor.

[0040] It can be understood that the rotating nozzle rotates and disperses the sprayed water column, and the dispersion of the water column can increase the contact area between water and air, thereby increasing the dissolved oxygen content in the water.

[0041] The algae removal mechanism 30 includes an algae removal box 31, an algae filter net 32 and an electric flocculation device 33. The water inlet end of the algae removal box 31 is connected to the water source, the water outlet end of the algae removal box 31 is connected to the water inlet end of the water spray pipe 20, and the sewage discharge end of the algae removal box 31 is connected to the sewage pipe.

[0042] It should be noted that the algae removal box 31 includes a box body and a box cover, and the box body and the box cover are detachably connected to facilitate the installation of other devices in the algae removal box 31. The algae removal box 31 can also be provided with a clearance hole to allow the devices inside the algae removal box 31 to communicate with devices outside the algae removal box 31. The water inlet and sewage outlet of the algae removal box 31 can both be holes or joints opened on the algae removal box 31. The holes and joints can be connected to the water pipe by welding, riveting, bolt connection, clamp connection, etc. The water pipe passes through the shell 11 and extends to the outside of the installation cavity 11a. To prevent water from entering the installation cavity 11a, the water pipe and the shell 11 are sealed. For example, a hole is provided on the installation cavity 11a for the pipe to pass through. The pipe and the hole can be sealed by welding, or a sealing ring can be installed between the pipe and the hole to achieve a sealed connection. It can also be other connection methods that can play a sealing role, which will not be repeated here; of course, the water inlet end and the sewage discharge end of the algae removal box 31 can also be pipes integrally formed on the box body of the algae removal box 31, and no specific limitation is made here.

[0043] The water outlet of the algae removal tank 31 and the water inlet of the water spray pipe 20 can be connected by screws, welding, riveting, or other methods. To prevent leakage, clamps, sealing rings, or other devices can be installed between the water outlet of the algae removal tank 31 and the water inlet of the water spray pipe 20. The sewage pipe is used to connect to the waste treatment equipment on the shore. Impurities in the algae removal tank 31 can be transported to the shore through this sewage pipe.

[0044] The algae filter net 32 is installed in the algae removal box 31 to filter the water discharged from the water outlet of the algae removal box 31. The algae filter net 32 can be set in various forms. For example, the algae filter net 32 divides the algae removal box 31 into two sub-algae removal chambers, the water inlet of the algae removal box 31 is set in one of the sub-algae removal chambers, and the water outlet of the algae removal box 31 is set in the other sub-algae removal chamber; for example, the algae filter net 32 is in the shape of a bag, which covers the port at one end of the water outlet of the algae removal box 31. The number of the algae filter nets 32 can be one or more, and the multiple algae filter nets 32 can be stacked layer by layer or spaced apart from each other, which is not specifically limited here.

[0045] The plates of the electro-flocculation device 33 are installed in the algae removal tank 31. Electro-flocculation wastewater treatment utilizes the anodic dissolution of aluminum or iron to generate highly active, multi-morphic polyaluminum or polyferric flocculants in situ. This process aggregates pollutant particles in the water and allows them to settle or separate via flotation. In the present invention, impurities such as blue algae in the algae removal tank 31 are allowed to settle and fall to the bottom of the tank 31, thereby facilitating more thorough removal of algae impurities within the tank 31. The plates of the electro-flocculation device 33 can be arranged in either a unipolar or bipolar configuration. Specifically, in a unipolar arrangement, all plates are connected to a conductor, while in a bipolar arrangement, only the plates at the two ends are connected to a power source. Preferably, the electro-flocculation device 33 is connected in a bipolar arrangement. In this bipolar arrangement, the plates at both ends are connected to a power source to provide a polarizing electric field without dissolution, while the plates in the middle dissolve due to polarization. This not only makes it easier to replace the plates, but also achieves a combination of electro-flocculation and electro-flotation. The anode plate material of the electro-flocculation device 33 can be iron, aluminum, or both iron and aluminum. Preferably, the anode plate is made of a combination of iron and aluminum, as this arrangement provides a better flocculation effect. The electro-flocculation device 33 can use direct current or pulsed current. Preferably, the electro-flocculation device 33 uses pulsed current, which can effectively suppress plate passivation and ensure good flocculation efficiency of the electro-flocculation device 33. To ensure that algae and other impurities are not attached to the plates of the electro-flocculation device 33, a protective net or other mechanism can be installed on the plates.

[0046] The water pump 40 is connected in series between the water inlet end of the water spray pipe 20 and the water outlet end of the algae removal box 31. The type of the water pump 40 can be a centrifugal pump, an axial flow pump or a mixed flow pump, etc., which is not specifically limited here.

[0047] The valve assembly includes a first control valve 50 installed at the water inlet end of the algae removal box 31, a second control valve 60 installed at the water outlet end of the algae removal box 31, and a third control valve 70 installed at the sewage discharge end of the algae removal box 31. The first control valve 50, the second control valve 60, and the third control valve 70 can be solenoid valves, pneumatic valves, or other valves that can control the opening and closing of the pipeline.

[0048] The controller 80 may be a PLC, a single-board computer, or other device known to those skilled in the art of electronics that has programming capabilities or is capable of controlling electronic components. Devices with such capabilities are within the scope of protection of the present invention. The controller 80 is electrically connected to the electro-flocculation device 33, the water pump 40, the first control valve 50, the second control valve 60, and the third control valve 70 to control the operation of the electro-flocculation device 33, the water pump 40, the first control valve 50, the second control valve 60, and the third control valve 70.

[0049] This solution connects the water inlet of the algae removal box 31 with the water source to draw water from the water source into the algae removal box 31; connects the water outlet of the algae removal box 31 with the water inlet of the water spray pipe 20 to input the water in the algae removal box 31 into the water spray pipe 20, and the water spray pipe 20 sprays the water back into the water body to oxygenate the water body; installs an algae filter 32 in the algae removal box 31 to filter the water discharged from the water outlet of the algae removal box 31; connects the sewage outlet of the algae removal box 31 with the sewage pipe to discharge the algae impurities in the algae removal box 31 to the water source; installs an electric flocculation device 33 in the algae removal box 31 to settle the algae impurities in the algae removal box 31, so that the algae Impurities are removed more thoroughly; by setting a water pump 40 connected in series between the water inlet end of the water spray pipe 20 and the water outlet end of the algae removal box 31, power is provided for the water entering the algae removal box 31 and entering the water spray pipe 20 and finally sprayed out; by setting a first control valve 50 installed at the water inlet end of the algae removal box 31, a second control valve 60 installed at the water outlet end of the algae removal box 31 and a third control valve 70 installed at the sewage discharge end of the algae removal box 31, and a controller 80 electrically connected to the first control valve 50, the second control valve 60 and the third control valve 70, the electric flocculation device 33, and the water pump 40 to control the working process of the algae removal oxygenator 100.

[0050] After the algae removal and oxygenation machine 100 has been working for a period of time, a large amount of algae plants are attached to the algae filter net 32, making it difficult to discharge the algae from the algae removal box 31 through the sewage outlet. As more and more algae are attached to the algae filter net 32, the algae filter net 32 is blocked, making it difficult for water to enter the water spray pipe 20 and be sprayed out, thereby failing to oxygenate the water body. The algae filter net 32 also loses its function of filtering algae. Therefore, in one embodiment of the present invention, please refer to Figure 2 The algae removal oxygenator 100 also includes an air pump 90, which is installed in the installation cavity 11a. The air inlet end of the air pump 90 is connected to the outside air through the shell 11, and the air outlet end of the air pump 90 is connected to the algae removal box 31 to blow off impurities attached to the algae filter net 32, thereby having a strong cleaning effect on the algae filter net 32 and ensuring the good working efficiency of the algae removal oxygenator 100.

[0051] It is worth noting that the position of the air outlet end of the air pump 90 is also closely related to the shape of the algae filter net 32. For example, when the algae filter net 32 is set to be bag-shaped, the bag mouth of the algae filter net 32 is connected to the water outlet port of the algae removal box 31, and the air pump 90 is connected to the water outlet end of the algae removal box 31, so that the air pump 90 can spray gas into the algae removal box 31 and blow the algae filter net 32 from the inside of the bag to the outside of the bag, thereby blowing off impurities attached to the outside of the algae filter net 32.

[0052] For example, if the algae filter 32 is in another shape, such as a sheet or plate, the algae filter 32 separates the algae removal box 31 into a plurality of sub-algae removal chambers. When the air pump 90 is connected to the algae removal box 31, it is only necessary to ensure that the ejected airflow acts on the side of the algae filter 32 opposite to the side where algae plants are attached, so as to achieve a better cleaning effect on the algae filter 32. Therefore, the air pump 90 can be connected to other parts of the algae removal box 31 besides the water outlet. The specific implementation is not repeated here.

[0053] The algae removal and oxygenator 100 further includes a fourth control valve 91, which is mounted at the outlet of the air pump 90. The controller 80 is also electrically connected to the air pump 90 and the fourth control valve 91 to control the operation of the air pump 90 and the fourth control valve 91. The type of the fourth control valve 91 can be the same as or different from that of the first control valve 50, and will not be further described herein.

[0054] The air pump 90 and the fourth control valve 91 can be manually controlled or automatically controlled. Manual control can be that the operator determines whether the algae filter net 32 is blocked based on the water flow rate sprayed from the water pipe 20, and then uses a remote control to control the start or stop of the air pump 90 and the fourth control valve 91. The remote control can be wirelessly connected to the controller 80 via Wi-Fi or Bluetooth.

[0055] Furthermore, the air pump 90 and the fourth control valve 91 are automatically controlled, please refer to Figure 4 The algae removal and aerator 100 further includes a flow monitoring device 101, which is electrically connected to the controller 80 and is used to detect the real-time water flow through the water spray pipe 20. The flow monitoring device 101 can feed back the detected result to the controller 80. The flow monitoring device 101 can cooperate with the air pump 90. When the feedback result received by the controller 80 is that the real-time water flow of the water spray pipe 20 decreases, the controller 80 controls the fourth working valve to open and controls the air pump 90 to start, thereby cleaning the algae filter 32 in the algae removal box 31.

[0056] The flow monitoring device 101 can be any type of sensor device, such as a volumetric flow sensor, a vortex flow sensor, a turbine flow sensor, an ultrasonic flow sensor, or a differential pressure flow sensor. It can also be an image detection device such as a smart camera. The flow monitoring device 101 can be installed in the water pipe 20 or outside the housing 11. Its installation position can be determined according to the specific sensor type used by the flow monitoring device 101. For example, it can use a volumetric flow sensor and be installed in the water pipe 20, so that it can sense the size of the water flow passing through. It can also use a smart camera and be installed outside the housing 11 to directly identify the size of the sprayed water column or water splash to determine the real-time water flow of the water pipe 20.

[0057] For further information, please refer to Figure 1 , the electric flocculation device 33 includes a power supply (unmarked), an anode plate (unmarked) and a cathode plate (unmarked). The power supply is installed outside the algae removal box 31. The power supply can be fixed on the outer wall of the algae removal box 31, or on the outer wall or inner wall of the shell 11. No specific limitation is made here. In order to prevent excessive algae and other impurities from adhering to the anode plate and the cathode plate, which causes them to be corroded or hardened. When the algae filter net 32 is set to a bag shape, the anode plate and the cathode plate are both set in the mesh bag of the algae filter net 32 and are electrically connected to the power supply through a connecting line; when the algae filter net 32 is set to a sheet or plate shape, the anode plate and the cathode plate can be set on the opposite side of the algae filter net 32 where algae and other impurities are attached.

[0058] The controller 80 is also electrically connected to the power supply to control the switching of the power supply.

[0059] It can be understood that the controller 80 can control the electric flocculation device 33 to be started at intervals. With this setting, on the one hand, the pulsed electric flocculation can improve the flocculation effect. On the other hand, during the oxygenation filtration, the water in the algae removal box 31 is constantly circulated and replaced. During this period, the start-up of the electric flocculation device 33 has no effect. Therefore, the oxygenation water spraying and electric flocculation can be carried out alternately.

[0060] In one embodiment of the present invention, please refer to Figure 3 The algae removal and aerator 100 also includes an electrolyte storage tank 102, which is used to store strong electrolytes, such as those containing chloride or sulfate ions. Wastewater containing excessive impurities has low conductivity, which increases energy consumption during electrocoagulation and leads to excessive electrode polarization, reducing removal efficiency and electrode life. Therefore, adding a suitable strong electrolyte to the wastewater can improve water conductivity, thereby increasing electrocoagulation efficiency and reducing energy consumption.

[0061] The outlet end of the electrolyte storage box 102 is connected to the algae removal box 31. The electrolyte storage box 102 can be installed above, around or below the algae removal box 31. It can be on the shell 11 located in the installation cavity 11a, or it can be installed on the shell 11 outside the installation cavity 11a. Preferably, the electrolyte storage box 102 is installed on the shell 11 in the installation cavity 11a and is located above the algae removal box 31, and the strong electrolyte can directly enter the algae removal box 31 by gravity. The algae removal aerator 100 also includes a fifth control valve 103, which is installed at the outlet end of the electrolyte storage box 102. The controller 80 is also electrically connected to the fifth control valve 103 to control the switch of the fifth control valve 103. When the fifth control valve 103 is opened, the strong electrolyte in the electrolyte storage box 102 flows into the algae removal box 31 by gravity. When the fifth control valve 103 is closed, the strong electrolyte in the electrolyte storage box 102 stops flowing. The type of the fifth control valve 103 may be the same as or different from the type of the first control valve 50 , and will not be further described herein.

[0062] In one embodiment of the present invention, please refer to Figure 1 In order to enhance the sedimentation effect of algae and other impurities, the inner diameter of the algae removal box 31 is gradually reduced from top to bottom and is funnel-shaped. The sewage discharge end of the algae removal box is set at the lower end of the algae removal box 31. Due to the action of gravity, algae and other impurities eventually slide into the sewage discharge end of the algae removal box 31 along the inclined wall of the funnel.

[0063] In one embodiment of the present invention, please refer to Figure 4 The algae removal mechanism 30 further includes an interception net 104, which is provided at the water inlet end of the algae removal box 31.
